Abstract
A Vee bottom planing boat hull (32) has right and left steps (44 and 46) positioned so as to optimize the boat's trim angle at top speed, and defining right and left notches (48 and 50) in which are pivotally mounted left and right tirm tabs (56 and 58) having forward leading edges (60 and 62) along oblique pivot axes (64 and 66) causing outer comers (102 and 104) of trailing edges (68 and 70) of the trim tabs to move downwardly more than inner comers (106 and 108) during downward pivoting of the trim tabs, providing an active hull to control boat trim angle and effectively reduce deadrise angle while maintaining a running surface trailing edge substantially free of discontinuities in the vertical direction.
